Perfect Binary Tree

Famous quotes containing the words perfect and/or tree:

    We love to see any redness in the vegetation of the temperate zone. It is the color of colors. This plant speaks to our blood.... What a perfect maturity it arrives at! It is the emblem of a successful life concluded by a death not premature, which is an ornament to Nature. What if we were to mature as perfectly, root and branch, glowing in the midst of our decay, like the poke!
    Henry David Thoreau (1817–1862)

    Our courage breaks like an old tree in a black wind and dies,
    But we have hidden in our hearts the flame out of the eyes
    Of Cathleen, the daughter of Houlihan.
    William Butler Yeats (1865–1939)
